Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable electronic device for automatically detecting whether the portable electronic device is carried or not carried on the body to inform a user of a more accurate physical quantity.

The physical quantity referred to here is time information, a natural environmental value such as temperature, atmospheric pressure, amount of ultraviolet rays, humidity, wind speed, gas concentration, direction, etc., mainly in a place where a person is active, or body temperature.
Indicates the biological information of the human body such as pulse, EEG, blood pressure, etc.

[0003]

2. Description of the Related Art In recent years, multifunctional timepieces have been developed for portable electronic devices such as electronic timepieces that can provide not only time information but more information. Among them, there are devices that have a built-in sensor in the watch body to measure and display physical quantities such as temperature, humidity, atmospheric pressure, and direction, and devices that measure and display biological information such as pulse and brain waves. Contributing to the creation of a healthy human living environment.

In order to enable these electronic devices to be used more accurately and for a longer period of time, it has been a problem to improve the measurement accuracy and operability of portable electronic devices in a portable / non-portable state.

Here, considering how a portable electronic device such as a watch is actually carried, a. Worn on the wrist b. Used in a pocket c. Neck strap Use it by hanging it with d. Carry it in your hand e. Put it in your pants pocket f. Use it around your waist belt g. Use it around your arm. In any case, the influence of body temperature on the sensor that measures the physical quantity is unavoidable.

Therefore, as a portable / non-portable automatic detecting means, for example, as shown in Japanese Utility Model Laid-Open No. 59-37587, the temperature is detected by a temperature sensor to judge whether or not it is carried on the arm. The method was taken.

Alternatively, for example, in a timepiece having a temperature measuring function, when a thermistor is used as a temperature sensor in order to accurately measure and display the temperature of the outside air, it must be left in a non-portable state for a certain period of time or longer. In order to bring the temperature sensor as close to the outside temperature as possible,
A sensor mounting structure as shown in FIGS. 2 and 3 of Japanese Patent Publication No. 984 has been devised.

[0008] In addition, at the time of temperature measurement
As shown in Japanese Patent Laid-Open No. 28, the measurement is performed by selecting whether the user uses the mobile state or the non-mobile state each time. When used in a portable state
As shown in the publication, a method of detecting a temperature difference and correcting the temperature is adopted.

On the other hand, with respect to a timepiece capable of measuring a physical quantity other than temperature, when the measurement is carried in a portable state, each sensor is affected by the body temperature, and therefore a body temperature correcting means is required. For example, when measuring ultraviolet rays, actual Kaihei 1-333627
As shown in Japanese Patent Laid-Open Publication No. 2003-242242, a method is provided in which a temperature sensor is separately provided to correct the measured temperature.

[0010]

However, the above-mentioned conventional technique has the following problems.

First, in the method disclosed in Japanese Utility Model Laid-Open No. 59-37587, a temperature sensor for detecting portable / non-portable must be provided, and the timepiece becomes thick. In addition, it is possible to automatically determine whether the device is carried or not carried only when it is carried on the wrist, and it is not possible to automatically detect the carrying or non-carrying in other carrying states.

It is also clear from experiments that the method disclosed in Japanese Utility Model Laid-Open No. 58-120984 cannot measure an almost accurate temperature because the outside air temperature and the portable temperature are above a certain level.

Further, in the method as disclosed in Japanese Utility Model Laid-Open No. 23-23328 and Japanese Utility Model Laid-Open No. 61-8846, when the temperature measurement is continued for a long time, every time the user takes off the watch or carries it. Moreover, the operation had to be performed to make the person aware of the state, and the operation was troublesome. Also, if you forget to operate or make a mistake, the corrected temperature is displayed even if you are in a non-portable state, or the temperature that you left while you are in a portable state is measured and displayed. I sometimes recognized.

Furthermore, in the method as disclosed in Japanese Utility Model Laid-Open No. 1-333627, temperature correction is possible, but since it is not possible to automatically determine the carrying / non-carrying state, the temperature is corrected with respect to the body temperature. It is not clear whether the temperature is corrected for the outside air temperature. Therefore, even when measuring physical quantities other than temperature for a long time,
The same problem as the above temperature measurement occurred.

[0015]

Therefore, the portable electronic device of the present invention automatically measures the physical quantity regardless of whether it is portable or non-portable. It is characterized in that a carrying determination means for determining is provided, and when the carrying state is detected, the physical quantity corrected by the body temperature correction means is displayed.

It is desirable to use 1. temperature detecting means 2. impact detecting means 3. biometric information detecting means as the carrying determination means. In this case, a. An electric signal generated in a piezoelectric element or an electric signal generated in an electromagnetic coil is used as the impact detection means, or b. A pulse, an electrocardiogram, an electroencephalogram, a pulse wave, or the like is used as the biological information detection means. Of the human body surface by infrared radiation as the temperature detecting means, or d. The impact detecting means, the biological information detecting means, and the temperature detecting means are used together. Instead of providing the component, the component already built in the portable electronic device may be used together to perform the detection.

Furthermore, in the present invention, in addition to means for automatically detecting the portable / non-portable state of the portable electronic device on the body,
It is desirable to provide a means for storing the value of the measured physical quantity and a means for displaying the stored value.

When the mobile phone determination unit 12 determines that the mobile phone is “mobile”, the arithmetic processing circuit 9 passes through the body temperature correction unit 13 and the decoder 14
Is input to the physical quantity storage unit 22 at the same time.
When it is determined to be “non-carrying”, the data is input to the decoder 14 and at the same time to the physical quantity storage unit 22 without passing through the body temperature correction means 13. Reference numeral 21c is a physical quantity storage display unit that displays the stored physical quantity value. When the operation switch 23 is turned on, the pulse signal K is sent from the timing signal generation circuit 19 to the physical quantity storage unit. This signal K is also sent to the arithmetic processing circuit 9 and inhibits output from OUT1 to OUT12 to the decoder 14. As a result, the value of the physical quantity stored in the physical quantity storage unit 22 is stored in the physical quantity storage display unit 21c via the decoder 14 and the driver 15.
Driven to. The physical quantity storage display unit 21c can also be used as the physical quantity display unit 21b.
